Abstract

Superficie estructurada (200) de un sólido con adherencia conmutable, en la que la superficie (205) presenta una estructuración que comprende una multiplicidad de salientes (210, 220) que presentan al menos cada uno de ellos un fuste (210, 220), y en la que el fuste posee una cara frontal (215, 225) que mira hacia fuera de la superficie (205), caracterizada por que la multiplicidad de salientes comprende al menos dos clases de salientes (210, 220) que se diferencian al menos en la altura vertical de la cara frontal (215, 225); y el material de los salientes (210, 220) presenta un módulo de elasticidad tal que, dependiendo de la carga, una o varias clases de salientes (210, 220) forman en sus caras frontales (215, 225) una fuerza de adherencia que es superior a la fuerza ejercida por la eventual compresión de los salientes (210, 220); y al menos una clase de salientes (220) presenta una relación de aspecto tal que, al sobrepasarse una carga determinada, se pandean estos salientes (220) y disminuye fuertemente la fuerza de adherencia por efecto del pandeo de las caras frontales (225).Structured surface (200) of a solid with switchable adhesion, in which the surface (205) has a structuring that comprises a multiplicity of projections (210, 220) that each have at least one shaft (210, 220), and in which the shaft has a front face (215, 225) that faces out from the surface (205), characterized in that the multiplicity of projections comprises at least two classes of projections (210, 220) that differ at least in the vertical height of the front face (215, 225); and the material of the projections (210, 220) has a modulus of elasticity such that, depending on the load, one or more classes of projections (210, 220) form an adhesion force on their front faces (215, 225) that it is greater than the force exerted by the eventual compression of the projections (210, 220); and at least one class of projections (220) has an aspect ratio such that, when a certain load is exceeded, these projections (220) buckle and the adhesion force strongly decreases due to the buckling of the front faces (225).
